The Dynamic Sciences PA-103 is a general purpose, broadband, high gain, bench top preamplifier. The PA-103 reduces floor noise and increases system sensitivity to low level signals during Electromagnetic Interference (EMC) testing. It also provides input isolation to your expensive test equipment. The PA-103 operates from 1 MHz to 1000 MHz.
The simple front panel consists of two 50 Watt matched BNC connectors for input and output. The preamplifiers were designed to have minimal gain variation for the entire frequency range to reduce EMC measurement errors.
The PA-103 is individually calibrated and the gain data is shipped with the unit. Power to the PA-103 is supplied by a 9 VAC, 1 AMP external wall mount adapter supplied with the preamplifier.
